The'feedho'pper 25 has a receiving iopeningBOintO whichany suitable delivery hopper ina y discharge-J It will thus :be seen that when grain-is put into "the; delivery hoppenit will be .fed fto' the "25. and from: 'thisiinto the huller to d upon thereby. A coVerplate 31 for I the blades 28 is formed with a substantially cylindrical flange 32 into which the hopper r shaft 7, the two being pinned or otherwise secured together. Preferably integrally formed with the plate 33 are comparatively narrow vanes 35, the same being arranged around the periphery of'the plate 33 as shown in Figs. 3 and 4. These vane's 35 have reinforcing braces 36 to insure that the vanes will not readily be broken off in event some hard article like a stone should get into-the machine. Attention is c'alledto the fact that the impact faces of the vanes 35 are not radial with respect to the shafts 6 and 7 and the hubs 27 and'3t but are set at such an angle that g the grain delivered'by the inner rotating elementwill' strike the fa'ces of these vanes 35 at nearly a right angle. This resultsin a harder blow being deliveredwith the consequent more complete removalof the hulls. Since the shafts, 6 and 7 are preferably run at a speed of 900 to 1,000 R. P. M. it will be seen that the force of impact is quite consid erable. As the outer rotating element is traveling at a considerable speed, the airand hulled grain are forced outwardly through f the hood 22Iand the suction created through the hoppertends to draw the grain into the inner element 26. Collars "37 held in place by suitable means such as set-screws, are provided to, hold the shafts 6 and 7 in adjusted positions and to permit relative adjustment "thereof so as to securea proper, relationship of these parts within the casing 18.' The inner edges of the vanes are not perpendicularto the lateral faces but are bevelled off so that their planes lie substantially in the direction which the grain travels in moving to- I ward the vanes 35. Thisjreduces to a minimum the number of imperfect impacts of the grains upon the blades or vanes.

: Various modifications of the structure disclosed have been contemplated. For'example,

theshafts 6 and 7 may be replaced by a solid .shaft-and a hollow shaft, the latter surround. ing the: former and serving as supporting means therefor. Each would be supplied 3 with a gearor'pulley-for the applicationof v 7 power. ,I-Iowever, this method of construc- 5O tion was'not found as satisfactory as the one disclosed herein. Another method of I applying-the power to the rotating elements is to omittheshaftsiand apply gears or pulleys to the flange 32 and boss 34 but this construction is not considered satisfactoryfl It is of course understood that the specific description of structure set forth above may be departed from without departing from the spirit of my invention as set forth in this.

specification and the appended claims.

Having now described my invention,"I

claim:

l. A seed huller comprising a casing for the reception of the seed to be hulled, and I pair of hulling members mounted therein and rotatable in opposite directions, said hulling members each comprising a supporting member having a thereon to engage the seed.

2. In a huller, a substantially cylindrical casing having a substantially tangentially arranged discharging spout connected to the periphery thereof, an inlet to admit seeds or grains approximately centrally of an end of the casing, a pair of oppositely rotating supporting members in the casing having seed engaging members thereon to catch and throw the seeds outwardly, the seed engagplurality of vanes i mg members of one supporting Inemberbeing arranged radially outwardly from those on the other member.

3. In ahuller, a substantially cylindrical casing having, a substantially tangentially arranged discharging spout connected to the periphery thereof, said spout having a downwardly directed discharging opening, an in} let to admit seeds or grains approximately centrally of an end of the casingya pairof oppositely rotating supporting members in the casing having seed engaging -meinberS thereon to catch and throwthe seeds outwardly, the seed engaging members of one supporting member being arrangedradially outwardly from those on the other member, the seed engaging members, on one supporting member having their outerends turned forwardly in the. direction ofrotation of said member so as to direct the seeds substantially perpendicularly against the faces of the other seed engaging memberspf 4. In a, machine of thecha-racter described,

a casing, rotating members therein, said 'membershaving vanes thereon, the vanes of one'member rotating a circle outside of the vanes of the other member and in the same plane, the outer ends of the inner vanes being curved forwardly in the direction of rotation thereof.

a casing, rotating members therein, said menn bershavingvanes thereon, the vanesofone member rotating in acircle outside of the vanes of the other member and'in the'saine, plane, the inner set of vanes having their "ends turned forwardly in the direction of rotation of said member so that the particles 5. In a machine of the character described,

thrown off thereby'will directed against I the outer-vanes at nearly a right angle." 6. In a machineof the character described,

- a casing," rotating members-therein, said members having vanes thereon, the vanes of one member rotating in a circle Outside of the vanes of the other member and-in the same plane, the outer set of vanes having their impact faces inclined toward the inner set of v vanes so that the seeds thrown ofi" by the inner vanes may strike them substantially at a right angle and the inner vanes having their outer extremities curved forwardly to give the seeds a forward directional discharge.

7. In an impact huller, a casing,a central rotating shaft therein, a hub secured to the shaft, substantially flat vanes extending substantially radially from said hub in planes longitudinal thereof, the shaft, hub and vanes being designed to rotate in one direction only and the vanes having their outer extremities bent forwardly in the direction of rotation of the shaft.

In witness whereof, I hereunto subscribe my name to this specification.
